曲线梁桥纠偏复位施工在杭甬高速的应用

The Application of Curved Girder Bridge's Deviation Correction and Reset in Hangzhou-Ningbo Expressway

针对杭甬高速宁波段大朱家跨线桥出现的非传统桥梁病害,按照病害类型及实际现状,采用小半径曲线梁桥纠偏复位施工措施治理通车状态下的桥梁。着重介绍了该方法的施工原理和施工工艺,加固后的桥梁结构运行良好,未出现明显病害,事实证明纠偏复位施工在治理高速公路小半径曲线桥梁上有着显著的效果。

According to the unconventional bridge disease in the Zhujia overpass of Ningbo section of Hangzhou-Ningbo highway,it was decided to adopt the construction measures for the correction and correction of the small-radius curved beam bridge. Compared to the traditional curve beam bridge correcting and resetting construction,this technology is under the control of the open state. The bridge has more important significance. This article focuses on the construction principle and construction process of the method. In the return visits after the completion of the construction year,the bridges responded well and the disease on the highway bridges had significant benefits and achievements.
